The Kaysuda camera driver acts as the essential bridge between Windows hardware and the advanced biometric authentication of the Kaysuda CA20 Face Recognition Camera Go to product viewer dialog for this item.
- Connect the camera and run
lsusb to see if it is detected.
- Install video utilities:
sudo apt install v4l-utils
- Check with
v4l2-ctl --list-devices.
- If not detected, you may need to compile a custom driver from source (available on GitHub for some Kaysuda industrial models).
Issue: The Video is Blurry or Stretched
This suggests the driver is installed, but the resolution settings are mismatched.

2. Stability and performance
- Latency and throughput: UVC modules are convenient but add USB stack overhead; MIPI/CSI offers lower latency and higher sustained bandwidth for high-resolution or high-framerate use.
- Frame consistency and exposure control: Some inexpensive sensors expose limited rails for manual control; others provide decent automatic exposure and gain. Stability depends heavily on the vendor-supplied register settings and any tuning firmware they include.
- Reliability: Reports from makers and small integrators indicate acceptable day-to-day reliability for general-purpose imaging, but occasional issues arise around driver regressions after kernel updates or when switching SoC platforms without vendor-supplied patches.
: If your laptop already has a built-in infrared camera, disable it in the Device Manager to prevent conflicts with the Kaysuda unit. 2. Manual Driver Activation
During testing, the following issues and limitations were identified:
